What should my friends do?

my friends let's call them veronica and herbert. they're room mates and they broke up with there bf and gf about 2 weeks ago and they wont leave. Veronicas ex is 33 and herberts ex is 21. v and h are both 21. V's ex sits around and watched disney all day so i told her she should block it. and H's ex sleeps in his bed and makes him sleep on the couch and when he tried to sleep in his bed she wanted to cuddle and asked him just to love her and he told her to leave. how do they get both of them to leave. oh and they both have keys to the apt and wont give them back
